Working principle
Multi-effect evaporation and TVR
Vapour from one effect heats the next at a lower pressure, concentrating effluent in stages. Thermal vapor recompression recycles vapour enthalpy via a steam jet thermocompressor, reducing live steam demand versus standalone MEE.
Our multi-effect evaporator (MEE) systems achieve high energy efficiency by reusing steam vapour across multiple effects. Used extensively for concentrating liquid effluents, producing ZLD (zero liquid discharge), recovering valuable materials from dilute streams, and concentrating food & pharmaceutical products. We design 2-effect to 7-effect systems with falling film, forced circulation, or rising film evaporator bodies.

FAQ
Technical answers — Multi Effect Evaporators
- What is the steam economy of a multi-effect evaporator?
- Steam economy depends on the number of effects, boiling-point elevation and the heat-and-material balance. We do not publish a single catalogue economy. Send feed rate, concentrations and available steam so the train can be engineered.
- Can MEE systems be used for zero liquid discharge (ZLD)?
- Yes. Multi-effect evaporators are a core component of ZLD systems, concentrating effluent for final crystallization or evaporation to dryness. We design complete ZLD trains.
- TVR vs MVR for ZLD?
- TVR uses motive steam to recompress vapour — attractive when HP steam is available. MVR uses electrical drives. We size TVR packages when the enquiry defines steam conditions; we do not assume a single ZLD architecture.
